Abstract: Single-failure criterion is the basic design principle of nuclear protection system, which ensures that the system can realize the safety function under the single-failure and ensure the nuclear safety. The test approach and test method under degrade-mode are designed based on "HPR1000" first reactor in this paper. Through the test analysis, it is verified that the system meets the single failure criterion, has the redundancy function, and meets the requirements of the design and regulations.
